Current Research

Aerothermodynamic Analyses for Planetary Entry Vehicles: This research involves the definition, analysis, and calculation of engineering and physics features involved in planetary entry science, and the high-temperature, shock-layer, radiative heating associated with planetary entry vehicles. The research supports NASA’s program to send entry vehicles to explore the Outer Planets, Venus, or Mars; and, Earth return from its moon or Mars.  The purpose of the research is to investigate the physics and chemistry of a high-temperature, reacting flowfield, and to define methods to accurately predict the heating and aerodynamics associated with these high-speed entries. Gaseous radiation is the major source of heating concerns at the higher velocity entries for the entry missions cited. Thus, investigation, analysis, and modification of current computational methods for gaseous radiative transport are of significant interest to insure a vehicle’s survival during entry.  Validation of developed analyses with existing ground-based and flight data is part of the research.  Also, the development of databases suitable for use in system design of potential missions and design of approved missions is included.
